Checkers' Dog

Checkers was meeting with the lazy Sorceress and Mr.Tin, two well known dog breeders.
They were just ending a conversation about politics when Mr.Tin asked Checkers if he had ever owned a dog. Checkers, trying to make it seem as if he knows something about dogs said, "Yes, I used to have a Basenji. He would always bark when someone was coming up the driveway." Mr.Tin and the lazy Sorceress knew he was lying and decided to leave. What did he lie about?
